+4C sequencing data.  @code{r-fourcseq} provides a pipeline to detect specific
+interactions between DNA elements and identify differential interactions
+between conditions.  The statistical analysis in R starts with individual bam
+files for each sample as inputs.  To obtain these files, the package contains
+a Python script to demultiplex libraries and trim off primer sequences.  With
+a standard alignment software the required bam files can be then be
+generated.")
